<h2>Answer with explanation:</h2>

1)

\dfrac{7x}{9}>\dfrac{-14}{3}

On solving we get:

x>-6

Hence, the shaded region is to the right of -6 with open circle at -6.

2)

\dfrac{-75x}{4}>\dfrac{225}{2}

On solving we get:

-x>\dfrac{225}{2}\times \dfrac{4}{75}\\\\\\-x>6

on multiplying both side of the inequality by -1 we get:

x

Hence, the shaded region will be to the left of -6 and open circle at -6.

( Since, the inequality is strict)

3)

\dfrac{x}{4}\leq \dfrac{-3}{2}\\\\\\x\leq \dfrac{-3}{2}\times 4\\\\\\x\leq -6

The graph of this will be  shaded region to the left of -6 and closed circle at -6.

Since the inequality is an inequality with a equality sign.

4)

\dfrac{2x}{3}>\dfrac{-16}{3}\\\\\\x>\dfrac{-16}{3}\times \dfrac{3}{2}\\\\\\x>-8

Hence, the graph is a number line with shaded region to the right of -8 and open circle at -8.

( Since, the inequality is strict )

The triangles below are similar because of the:
STALIN [3.7K]

Answer:

ΔABC and  ΔXYZ are SIMILAR by SSS property of similarity.

Step-by-step explanation:

SSS Similarity Theorem:

Two triangles are said to be similar if their  CORRESPONDING SIDES are proportional.

In ΔABC and  ΔXYZ, if \frac{AB}{XY}  = \frac{BC}{YZ} = \frac{AC}{XZ}  , then  △ABC∼△YZX

Here, in ΔABC and  ΔXYZ

AB = 9, BC = x , AC = 12

Similarly, XY = 3, YZ = 2, ZX = 4

Here,

\frac{AB}{XY} = \frac{9}{3}  = 3\\\frac{BC}{YZ} = \frac{x}{2} \\\frac{Ac}{Xz} = \frac{12}{4}  = 3

⇒ Corresponding sides are in the ratio of 3, if BC  =6 units

Hence, if BC  = 6 units, then the ΔABC and  ΔXYZ are SIMILAR by SSS property of similarity.
